WRIST WATCH BAND Filed April 30. 1926 Patented Oct. 29, 1929 EDWARD F. HERSCHEDE, or'` cmcrNNarLomo WRIST-WATC'HBANDJ Application filed April 30,

This invention relates to wrist straps and fastening means thereforand has for an object the provision of a simple and adjustable securing means.

Another object is to provide a structure of the class referred to which is inexpensive of manufacture and assembly.

Another object is to provide a structure of this kind which is adaptable to use with wrist straps of solid metal, tortoise shell or other substances of suitable characteristics.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings, in which Fig. 1, is a perspective view of a wrist watch and strap having a device of my invention embodied therein. j

Fig. 2, is a cross sectional view on line 2-2 of Fig. 1. Y

Fig. 3, is a similar view showing a modified form of the device of my invention.

Fig. 4, is a cross sectional View showing another modified form of the device.

A wrist watch case 8 carries at its opposite` sides pins 9 for mounting the wrist strap or bracelet members'l() and 11. The strap portions 10 and 11 may be made of flat strips of suitable material finished uniformly or in contrast with the case 8. Tubular portions 12 on the ends of members 10 extend between the lugs 13 on the case and receive the pins 9.

The free end 14 of member 11 has a perforation 15 and a communicating reduced aperture therethrough forming'V an opening for receiving a headed stu-d adjustably retained on the strap member 10. The member 10 as shown in Figs. 1, 2 and 3, has a plurality of spaced perforations 17 therethrough aligned with aperture 16 in member 11. The

perforations 17 are omitted in the modification shown in Fig. r4.

A flat C-shaped` clamp 18 of resilient or bendable material has a body portion 19 which rides against the outer face 20 of member 10 f and has curved lugs 21-eXtending` about the opposite edges 22 of said strap member. The lugs 21 abut the inner face of the strap 10, and in the structure shown in Fig. 4 yfrictionally bind the clamp 19 thereto.y This form is pref! 5o erably made of metal. A stud 23 extends 192e. "serial No; 105,829. y

through andl isy secured in the clamp 19 ywith f shouldered portion 24`abutting the outer face n ofthe clamp. Shoulder/24 is of a diameter such as to be slidably received in' aperture 16;

A head 25 on stu-d 23is adapted to be passed 55 through al perforation 15A and rides over ythe top face offstrap member 1'1' as shoulder 24 enters aperture 16. Inrthis' way thestrap i members aresecured togethenwhen placed about the wristof a wearer; f y60 In the formsshown in Figs. 1, 2and 3, the y stud 23 has an end lug v26`proje`cting through the clamp 18 and 'seating in a selected one of perforations 17 to preclude movement of the clamp relatively to member j10. 4In these 65 n embodiments' the clamp maybe compara-l tivelyliexible so that the end lug may be with@l drawn by pulling the clamp slightly away f from the strap, the flexibility vof the yclamp permitting theflimited movement required.

In the embodiment shown in Fig. 4, the frictionalfengagement'of-the clamp on the strapk is suchas tol permit adjustment but to preclude slippage. 1

The partsbeing of comparatively thin maj,

terial provide a light weight and comfortable strap which is adapted to be easily adjusted to lit the wrist. The strap members may be curved and the normal resiliency of the may terial permits them to conform to the Wrist when'the clamp is in any of its adjusted positions. The securing means is` posit-ive and easy to open and close. f f j From the foregoing ,they operation of the device isapparent. The strap ends are overg5 lapped to permit entry of head 25 through aperture 15, whereupon theshoulder 24 enters aperture 16. y i f The straps and clamp maybe of like or dissimilar material, it being essential onlythat y9o the materialsbe flexible or bendable but rigid enough to retain the'desiredshape.I

What I claim is: j 1. In a device of the class described they combination of a pair of strap members adapted to overlap one another at their free ,y

ends, one of said members having a series of longitudinally spaced perforations therein,

- 'the other member having a single opening adjacentits end and aligned with the perfora- Y 2 Y Y 'Y 1,733,538

tions in the first mentioned member, a clamp member on the iirst mentioned member and having curved lugs extending about opposite side edges of said member, a stud extending through the clamp and having one end seating in a selected one of the perforations in the strap member, and aspaced head on the other end of the stud for entry into the, single opening in the n second mentioned strap member. Y'

2. In a device of thev Zclass describedv the combination of a Wrist strap member having e r longitudinally spaced perforations therein,`Y a bendable clamp member comprising a body disposed transversely across one face of the l strap and slidable longitudinally thereof and I resilient lugs extending about opposite edges of LtheYst-rap and engaging the opposite face thereof, a lug on the clamp for entry inthe perforations in the lstrap* for vprecluding slidable movement oftthe'clamp, ra second strap for overlapping therstmentioned strap and cooperating means on said strap and clamp for locking the strap; members against longi- 25 tudinal separation.- Y f 3. In awrist watch strap construction the combination of arrstrap having perforations therein, a C-shaped clamp Vmember slidably carried by saidy Strap and a stud fixed inthe Y gclamp member and having ends extending in opposite directions therefrom, one of'Y said ends serving to enter, a perforation in the strapito ix the @clamp against longitudinal movement thereon, the other of said yends 35 serving to detachably connect a second strap to the clamp. Y

In testimony whereof, I have hereunto subscribed my name this 26th day ofApril, 1926. ff
